Running bamboo is notoriously fast spreading and difficult to remove. What keeps its population balanced in the wild, and prevents it from crowding out the competition? I tried googling, but was inundated with gardening advice, horror stories, and assault / offensive gardening (some of the latter two presumably covering the same incident from both sides). My google-fu failed, I couldn’t really find any info about natural population controls of running bamboo in the thicket of tall tales and gardening advice.
Climate for one. At least where I’m at its too cold for bamboo to grow. Even in peak summer it’ll try to spread but its only a matter of time till the frost destroy it.
Now kudzu on the other hand. That shit is fucking up everything.
